Abstract
Some embodiments include a flow regulator with a main body dimensioned to be received within a flow passageway that includes an inlet and an outer surface, and an inner volume positioned within the main body and extending from the inlet along at least a partial length of the main body. Some embodiments includes two separate spiral structures positioned spiraled around the main body where one spiral extends further from the outer surface than the other. Some embodiments include a fluid flow space extending between the spirals. Based on a fluid pressure, the spirals can expand and contract to control the fluid flow space and affect downstream, fluid flow rate as a function of upstream fluid pressure.
